JIGSAW ACTIVITY This cooperative learning activity involves splitting students into groups of five. Each group will work together to become ‘experts’ on their given topic. Students will use their textbooks and any other available resources to engage in a group discussion. Each group will be required to research what key events occur during their particular stage. Students will then regroup with one expert representative in each group and exchange information with their peers.
GROUP 1- INTERPHASE
The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division). Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible. The cell may contain a pair of centrioles (or microtubule organizing centers in plants) both of which are organizational sites for microtubules
GROUP 2-PROPHASE
Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nucleolus disappears. Centrioles begin moving to opposite ends of the cell and fibers extend from the centromeres. Some fibers cross the cell to form the mitotic spindle.
GROUP 3-METAPHASE
Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase plate. This organization helps to ensure that in the next phase, when the chromosomes are separated, each new nucleus will receive one copy of each chromosome.
GROUP 4- ANAPHASE
The paired chromosomes separate and move to opposite sides of the cell.

GROUP 5- TELOPHASE
Chromatids arrive at opposite poles of cell, and new membranes form around the daughter nuclei. The chromosomes disperse and are no longer visible under the light microscope. The spindle fibers disperse, and cytokinesis or the partitioning of the cell may also begin during this stage
